Harry Meade & Rosie Bradford’s Wedding – October 2010

One of Kate’s earliest appearances with Will was at Harry Meade and Rosie Bradford’s wedding in October 2010. She wasn’t yet engaged to him, but it was clear to the public that the duo was in a very serious relationship. For the wedding, Kate wore a blue satin dress paired with a blazer and a fascinator. The look is simple and polished, but it was clear from the photos released from the event that she felt uncomfortable and was constantly fiddling with her fascinator.

Engagement Announcement – November 2010

Just one month following the wedding appearance, Kate and Will stepped out together to announce their engagement. For the appearance, Kate wore a long-sleeve blue dress with ruching on the waist. The dress immediately sold out everywhere and is one of her most iconic looks to date. It’s safe, elegant and fits her well.

In December 2011, Kate stepped out wearing this olive green sweater dress while visiting a homeless charity in London. She paired the look with a thick black belt, opaque tights, and knee-high boots. This casual look is definitely reflective of its time and not something we’d imagine that Kate would wear today.

Amundsen Centenary Race – April 2012

One of Kate’s signature ensembles is a matching tweed suit! She’s worn this look on multiple occasions throughout the years, even as early as 2012! Tweed suits are polished, professional and chic, so we can certainly see why this has been a go-to favorite of hers throughout the years. By 2012, Kate’s style had certainly become more regal and formal.

In 2013, Kate and Will announced that the Duchess was expecting their first child. Kate’s fashion evolved once again while she started incorporating maternity and A-line pieces into her wardrobe. This emerald look she wore to a St. Patrick’s Day service in 2013 is the epitome of Kate’s maternity style with its flared skirt and collared neckline.

Prince George’s Birth – July 2013

In July 2013, the royal duo stepped out to present their firstborn, Prince George, to the world. For the occasion, Kate wore a cornflower blue shift dress with white polka dots. It was widely assumed that the look was in honor of Princess Diana, who wore a similar teal dress while presenting Prince William to the world. Re-creating some of Diana’s iconic outfits is something that Kate has done often throughout the years!

Stephen Lawrence Centre – March 2015

In March 2015, Kate was pregnant again with Princess Charlotte. For her second pregnancy, she recycled quite a few of her past maternity looks, but one of her most memorable was this bright fuschia wool coat.

XLP Project London Wall – March 2016

One thing that hasn’t changed for Kate’s style throughout the years is her love of tweed. In March 2016, she stepped out wearing an orange printed tweed dress in a sophisticated houndstooth print.

A Street Cat Named Bob Premiere – November 2016

Hamburg Germany Visit – July 2017

In July 2017, Kate and William visited Hamburg, Germany. For the occasion, Kate wore one of her most memorable ensembles of all time: this lavender-colored A-line dress. She’s repeated it a few times throughout the years and is definitely one of her most recognizable looks.


Paris Tour – March 2017

In 2017, Kate stepped out wearing this sleek aqua blue dress that was covered in beading and gemstones. This is definitely one of her more glitzy looks, but we love that she wore it in Paris, which is certainly a location deserving of a dress this fabulous.


World Mental Health Day – October 2017

In 2017, Kate stepped out wearing a lace blue dress with black detailing that definitely received mixed reviews. While Kate’s style leans towards the more polished and sophisticated side, many began questioning whether her style was a little too safe and overly mature for her age.

Prince Louis’ Birth – April 2018

In April 2018, Kate stepped out wearing a red post-baby look for the duo’s third child, Prince Louis. The look was inspired by the red dress Princess Diana wore when she presented baby Prince Harry to the world. Kate, of course, updated the look with a chic lace peter pan collar.


Remembrance Day – November 2018

In November 2018, we began to see a new revelation in Kate’s traditional style. Perhaps Meghan Markle inspired her to begin dressing a little more trendy, but Kate looked gorgeous when she stepped out in this emerald coat dress in November 2018. In the past, Kate didn’t stray from classic shapes and pieces, so it was refreshing to see her incorporate such an in-the-moment trend like this padded velvet headband.
